Abstract: In this paper, authors have proposed a controller based framework having transmission flow for query search and/or query responses. In this approach, total structure is divided into number of levels, and each level has two set of controllers. Servers are worked together in each set of controllers. Servers are heterogeneous in nature based on functionality and configurations. Server selection in each level, communication establishment, and transmission of information between two servers placed at two consecutive levels are three major tasks to be executed for entire query search processing. Several policies are proposed for communication establishment and transmission of information between servers with consideration of risks management. Several load management strategies have been proposed for server selection dynamically from set of available servers having distinct loads using load balance factor. In this paper, we have also introduced a procedure to follow two separate paths for transmission of search query and query response to avoid congestion in network to achieve minimum delay in query response.
